Diverter Flap Valve

Most gas handling systems have a requirement to change the gas flow direction to allow access to critical components, without shutting down the whole plant. With traditional dampers there is the danger of an upset, or explosion, if the two dampers do not act simultaneously. The FOURESS Diverter Valves was developed to handle such a situation in gas-turbine installations which incorporates a heat recovery boiler. Subsequently the concept has been used in a wide variety of industrial applications, such as refinery heat recovery plants, pollution control and nuclear ventilation systems and D.G Sets.
